1989 Chevy Silverado - metal Debris - Photo 04

Once the pumpkin was drained, we noticed a large amount of metal debris attached to the magnet inside the bottom of the center section. (We like magnetic drain plugs because they give us a clear picture of how much wear occurs inside a differential over time.) This truck had roughly 135,000 miles on the odometer. The vehicle's owner told us that the gear oil was changed twice during the truck's life, so this much-needed overhaul was, in fact, perfect timing for our donor truck.
